Ram Update Question

[ryanshafer]

hey,
i have a question referring to ram updating. i have a imac g5 1.8ghz... my current ram is one 1gb pc3200 ddr and 256MB pc3200 ddr. i want to switch my 256mb with another 1gb module. I recently bought a 1gb pc2700 drr ram module that was on sale, my question is will this work with my current setup and if it does work.. will it make much of a difference or will it slow it all down because of the pc2700 and pc3200 difference? i don't want to open the package and try because then i wont be able to return it. thanks in advance

Don't use the PC2700. I'm not sure about Macs, but in the PC world, RAM is as fast as the slowest module. Meaning your PC3200 will be clocked down to PC2700.

Same is true with Macs. It will clock the rest of the RAM down to PC2700. So you'll lose some performance. Take it back and get DDR400 (aka PC3200). Make sure NOT to get DDR2 RAM which is different from DDR RAM.
